JOSQ Y-I I E .OGLE & PHILIP HAYDNRICKETT THEIR ATTORNEY United States Patent 3,425,255 ROLLING MILL Joseph Eric Ogle, Sheflield, and Philip Haydn Rickett,

Rotherham, England, assignors to Davy and United Engineering Company Limited, Yorkshire, England Filed Oct. 24, 1966, Ser. No. 588,844 U.S. Cl. 72-238 7 Claims Int. Cl. B21b 31 /12, 31/20, 29/00 ABSTRACT OF THE DISCLOSURE In a preferred form the invention provides a combination beam and section mill including beam roll guiding cheeks slidably mounted vertically in the mill housings, so as to extend parallel to the horizontal rolls and bridge the housings, each cheek being slidable between a beam mill position adjacent the roll gap and a section mill position permitting access to the roll gap.

The invention will be more readily understood by way of example from the following description of a combination beam and section mill in accordance therewith, reference being made to the accompanying drawings in which:

FIGURE 1 is partly a front view and partly a sectional view of the mill, when arranged to roll beams and,

FIGURE 2 is partly a side view and partly a side sectional view of the same mill.

The present invention is not primarily concerned with the detail of the beam mill. It is therefore, necessary only to explain that the mill has a pair of housings 12, 13 each having a window 14, in which are located upper and lower beams 15, extending between the housings 12, 13 and transferring the rolling load from the horizontal rolls 16, 17 supported in horizontal roll chocks 16A, 16B to the housings 12, 13. The mill has also vertical rolls, one of which is shown at 17A mounted in its chock 17B at the right-hand side of FIGURE 1. The chocks are displaced from the planes of the housings towards the centre of the mill so that the housings provide no horizontal support for the chocks.

Also carried between the housings 12, 13 are a pair of cheek plates, one of which is seen at 18. Check plate 18 is carried by the housings and extends between the housings, parallel to the axes of the horizontal rolls and in its beam mill position lies adjacent but above the pass-line. The other cheek plate is disposed at the other side of the window 14, i.e., on the other side of the roll gap. These cheek plates 18 engage the upper horizontal chocks and the upper edges of the vertical roll chocks 17B to provide horizontal support for the chocks. Below the passline but adjacent thereto projections 18A at each side of the mill extend from the housing posts across the space between the housings and correspondingly engage the lower horizontal roll chocks and the lower edges of the vertical roll chocks.

Each cheek plate 18 is mounted for vertical sliding movement relative to the 'housings 12, 13, the cheek plate ends being disposed in slots 19 formed in the housing posts. Each plate 18 is attached by rods 20 to two piston and cylinder arrangements 21 which are secured to the 3,425,255 Patented Feb. 4, 1969 housings 12, 13 by brackets 22, for eifecting the vertical sliding.

When the mill is to roll beams, the cheek plates 18 are as shown in the drawings, i.e., in their lowermost positions guiding and supporting the chocks 16A, 16B and 17B. On the other hand, when section is to be rolled, the horizontal rolls 16, 17 and the vertical rolls 17A are replaced by a pair of horizontal section rolls, the chocks of which are supported by the housings so dispensing with the guide function of the cheek plates 18, and the piston and cylinder arrangements 21 are operated to withdraw the cheek plates 18. upwardly and thereby give access to the section mill roill gap.

It will be appreciated that other methods may be employed for moving the cheek plates 18, as for example, by latching the cheeks to the roll balance gear (not shown). Wedges may be used to locate the cheek plates 18 in their proper positions when they are in the lower positions set for beam rolling.

In accordance with the provisions of the patent statutes, We have explained the principle and operation of our invention and have illustrated and described what we consider to represent the best embodiment thereof.

We claim:

1. A combination beam and section mill including beam roll guiding cheeks slidably mounted vertically in the mill housings, so as to extend parallel to the horizontal rolls and bridge the housings, each cheek being slidable between a beam mill position adjacent the roll gap and a section mill position permitting access to the roll gap.

2. A combination beam and section mill comprising a pair of housings, upper and lower horizontal beam rolls mounted in horizontal beam roll chocks, vertical beam rOlllS mounted in vertical beam roll chocks, the chocks being displaced from the planes of the housings towards the centre of the mill, and support means projecting across the space between the housings at each side of the mill, the support means including cheek plates mounted in the housings and vertically slid-able between a beam mill position adjacent the roll gap and a section mill position permitting access to the roll gap.

3. A mill according to claim 2 including upper and lower beams bridging the housings to transfer the rolling load from the horizontal rolls to the housings.

4. A mill according to claim 2 in which in the beam mill position the support means engages all the horizontal and vertical roll chocks.

5. A mill according to claim 2 in which the cheek plates are located above the roll gap and are arranged in their lower beam mill position to engage the upper horizontal roll chocks and the upper edges of the vertical roll chocks.

6. A mill according to claim 2 in which the support means includes projections from the housing posts below the pass-line arranged to engage the lower horizontal roll chocks and the lower edges of the vertical roll chocks.

7. A mill according to claim 2 including piston and cylinder assemblies mounted in the housings for effecting vertical sliding of the cheek plates.
